This ultegra cassette not only gave me the correct size and quality performance over my old shimano hyper glide cassette , but what makes me be totally satisfied with my purchase is that I'm saving around 100 gr . I appreciate it so much , thank you probikekit

Great product, unbeatable price

The 11-23 combo is perfect for the flat roads I ride in FL. Ultegra is easy to install and very smooth shifting. I haven't seen cassettes at this low a price, an excellent value, maybe because 11 speed is becoming the new standard. I bought a couple to get me through the next 30,000 miles and am considering a second order. Just a note: it might take a while to receive yours although mine arrived just a day after the estimated delivery date. Don't wait until the last minute.

upgrade

It was time to change out my Shimano 105 cassette, so I decided to upgrade to an Ultegra. I had one on my Trek and it work good. I have installed this one on my new carbon wheels. I haven't tested it yet, but I know it will performed good.

Quality and Quietly Smooth

This cassette is strong, shifts quickly and quietly when properly tuned. The weight savings over Dura-Ace is not going to be felt (certainly there are better ways to save weight--like put less water in your water bottle.
Amazing value for the price and rock solid.

Nice 10-speed cassette

If you are riding a Shimano 10-speed drivetrain then this is pretty much the best cassette you can get. It comes with a 1.86 mm spacer so that the cassette can also be mounted on wheels designed for 11-speed cassettes. Easy to mount.

Great cassette at a very good price

I ordered this cassette for a friend who had some seriously-worn cogs on his old Ultegra 6700 cassette on his race wheelset. New cassette + new chain = crisp shifting again. PBK's price was unmatched, and delivery was on-time.

Ultegra Cassette

After my local bike shop indicated I needed a rear cassette and chain I starting comparing the pricing and was very impressed with ProBikeKit. Placed my order and 10 days later it was on my doorstep at a significant savings from my local options. Both the cassette and chain were in original Shimano packaging and in excellent condition. They have now been installed and have made the shifting much smoother. Would highly recommend as long as you have the time to wait.

CS-6700 Ultegra Cassette

Bulletproof! I'm not sure why you'd go to Dura Ace on this kind of part. Not a component you want to shave weight on. I run Ultegra or 105 on all my bikes and they wear very well and last. Good value for the money.

Lightweight-Great Gearing

I purchased this cassette for two reasons. . . 1. I needed an additional cassette for my backup wheelset 2. I LOVE having 12-30 gearing! I chose this cassette because of it's weight (12-30 is 270g) my Tiagra 12-30 was over 340g. It shifts very smoothly but my rear deraileur needed adjusted slightly. Not sure why considering they were both the same exact gearing? If you haven't tried 12-30 gearing yet, you will probably love it. I have rather strong legs but the object is to work smarter, not harder on those ridiculous climbs. I could have went with a Sram 11-32 but I would have felt like a school girl spinning a 32 teeth cog :) Great Shimano quality, decent weight, excellent price, attractive ratios. Try one out!

Ultegra 6700 Cassette

These are the ideal compromise of weight vs. durability for a cassette for the recreational rider. 30 tooth gear on this cassette is a great ace in the hole if the hills get too steep or the rider too tired. These were provided as loose parts in a plastic bag like OEM parts would be packaged. This was not stated in the description but at the low price they were offered at, I would have purchased them anyhow. Missing the box is no big deal, but I like to have the plastic center piece to stack the pieces on after I wash them and before transferring them back to the freehub. If you have a 10 speed Shimano drive train this Ultegra cassette is a great deal that won't hinder performance.

A clear choice for value

I have Dura Ace equipment on my road bike and SRAM force and rival mix on my cross bike and on both, when the cassettes needed replacing, I tried the Ultegra level cassette.
As compared to the Dura Ace option, the Ultegra is much better value. It is nearly as light, and appears to last a little longer in use. For my SRAM group, oddly, I find the Ultegra cassette shifts more smoothly but that could be because my bike could have been spec'd had a lower spec SRAM cassette.
This cassette is a great piece that is a solid value and the performance is also very good.

Stimson cassette 12-30

Put it on right after I got it. A 35 miles ride tells everything. I went uphill without any problem. Did not use too much power as before. This can help me to take easy on my knee which I am having problem now. Love it and will get another one for my other bike. Will have a hilly ride this weekend and I believe this new cassette resolves my problem.

Best Cassette ever!

Nice

Nice add on to be able to spin up climbs. After all how many leg presses do you have per day? The body is a much more efficient cardio machine than it is muscular. Spinning is winning, I threw this cassette 12x28 on my race bike and I dig the extra climbing gears. If you were concerned about the top end and needed an 11 tooth, you could always swap it out. Works with my normal sized rear derailleur.

accurate, crisp shifting

I've been using Shimano Ultegra components on my bikes for the last 15+ years. I've never had a component related failure. With regular cleaning and lubrication I have been able to get in excess of 10,000 miles on an Ultegra cassette before I noticed a significant drop-off in performance. I don't have a bottomless bank account, so I chose to go with the modestly priced Ultegra component group over the Dura-Ace. Yes, the Ultegra is a bit heavier, and the finish detail is not as sexy but it's every bit as performance oriented and reliable as the Dura-Ace for much less money. And over the years Shimano seems to trickle down technology and design features from Dura-Ace to Ultegra and even 105 so that the differences become less noticeable. For the price that PBK sells this cassette it was an absolute no-brainer for me. I bought an 11-28 to compliment my 12-25 and provide more gearing options for the rides with significant elevation gain !

Great Cassette

1. Great price from Probikekit as always.
2. Light weight and has the right combination 11-28 to go with my compact crank 34/50. Without this, I wouldn't be able to get to the ski lift at Mount Baldy in southern California. Overall, it is a great cassette to have on days where you have long climbing ahead.

This cassette is perfect for both racing and training. its durable and has great longevity while being stiff, smooth, and light. its also a great upgrade if you are currently running a 105 cassette.
Definitely a must have for this price.

happy significant other

As the lady friend added road cycling to her biking repertoire, she missed the uber low gearing of her mountain bike. Even the compact/28 tooth cog left her feeling strained on some of the bigger hills in the area. After a determination the rear 105 derailleur could support the larger 30 tooth cog, the change was academic with a slight readjustment f the 'B' screw and was well received (if only the psychological benefit.) Personally, while there is a quality and weight enhancement moving from the 5700 to 6700 cassette, I personally like the gear spacing better . . . so much so I changed out the 12-27 on my 'cross bike with this cassette (total order of 3 cassettes.) For me, it provides the better ratio steps to 27 teeth with a 'bail-out' 30 for old guys like me in the sand and deep mud. Shimano quality, great price, and problem solved.

This will make our mountains a little less painful!

I am in the process of replacing the drivetrain's critical (and worn) components on our road tandem and, for the cassette, rather than replace-in-kind, I chose the Ultegra 12-30T cassette. That because the 30T big cog will make riding around in the mountains of Western North Carolina a lot more pleasant! That benefit on top of a great price and on-time delivery, Thanks!

I ride on all Dura Ace components except for the cassette and chain which I typically ride on Ultegra 6700/6701. They are more cost effective and the quality is just the same, ie, quality in shifting, etc. The weight saving won't help you go any faster.

Great cassette, great price

I got a new wheelset and wanted to avoid swapping cassettes around too much... but didn't have the money to buy a cassette at retail pricing. ProBikeKit's pricing (and free delivery... and free bonus gifts) made the purchase easier to "sell" to my better half. Delivered within the estimated timeframe in good condition. (Have since ordered another CS-6700 cassette 12-30T to have on hand for those "sufferfest" days here in the mountains of western North Carolina, upstate South Carolina & eastern Tennessee when facing sustained gradients of 16-20+ percent.

Never disappoints

This is a great cassette, it is durable, quiet and an excellent value. I bought these for my aero wheel so i could switch wheels as needed and since I had so much with luck with them on my regular road wheel

Great value

I received the Shimano Ultegra CS-6700 Bicycle Cassette for the best price from PBK for this smooth cassette! Now I can climb without hurting my middle age knees. Using this with 6600 front and rear derailleurs and YBN chain, I have no problems mixing component series, so go for it.

uphill CHALLENGED

First of all this site rocks, fast shipping and quick response to all my inquiries, also cheaper compared to most of the seller online.
As soon as this cassette was installed to my BIANCHI C2C I tested it and went ahead to climb the hills that was almost impossible for me to reach the peak with my old 6600 11-25t. To my suprise it was not a battle anymore, was able to complete my usual route with no stopping mid-way nor felt exsausted.
Over all, to me it is an excellent upgrade to my bike in regards to ascending ride.
Highly recommend to older riders (50 + yrs old like me) or to any rider who are struggling uphill.
